摘要： A hybrid electric vehicle and a method of controlling the same are provided to avoid a collision thereof attributable to erroneous operation of an accelerator pedal. The method includes determining whether an accelerator pedal is erroneously operated in the situation in which an obstacle is detected to be present in the traveling path. In response to determining that the accelerator pedal is erroneously operated, the method includes switching the driving mode to a mode in which an engine is disconnected from a driving shaft and a motor generates driving force. The number of revolutions per minute (RPM) of the engine is then adjusted based on the extent to which the accelerator pedal is operated and the torque of the motor is adjusted based on a first vehicle speed and the distance to the obstacle.

摘要： Provided is a method and a system for controlling engine start of a hybrid vehicle based on acceleration demanded power of a driver. More specifically, a variance of an output signal of an accelerator pedal sensor (APS) senses manipulation of an accelerator pedal reflecting an acceleration demand of a driver. When the variance of the output signal of the accelerator pedal sensor is a positive threshold value, acceleration demanded power corresponding to the output signal of the accelerator pedal sensor is calculated in a section in which the variance is positive and the calculated acceleration demanded power is accumulated. The accumulated acceleration demanded power is then compared with a set power value, and the engine is started to switch from the EV mode to the HEV mode when the accumulated acceleration demanded power is equal to or greater than the set power value.

摘要： The present invention relates to an anti-jerk control apparatus and method for an Hybrid Electric Vehicle (HEV).The anti-jerk control apparatus includes a model speed calculation unit for calculating a model speed of the motor in a state in which a vibration of a drive shaft is not considered. A vibration occurrence determination unit detects a speed vibration component while calculating a reference speed difference and an average speed difference from differences between the model speed and an actual speed of the motor, thus determining whether a vibration occurs on the drive shaft. A torque correction value calculation unit calculates a motor torque correction value for anti-jerk required to damp the vibration of the drive shaft, and controls torque of the motor if the vibration occurrence determination unit determines that the vibration occurs on the drive shaft.
